ROANOKE, Va. – Following a picture perfect Sunday, the picture for Monday isn’t as great. A Flood Watch is in effect for most of the region, starting at 8 a.m..
A Flood WATCH will go into effect at 8 a.m. for the counties shaded in green. 1 to 3" of rain could fall by Tuesday morning with localized higher totals possible. Strong to severe storms cannot be ruled out. Get the latest on 10 News at 11. pic.twitter.com/qDzo5RX4dd— Delaney Wearden (@DelaneyWearden) August 31, 2020
The same high pressure system that kept us comfortable Sunday will work against us. As low pressure sends moisture over a front and into our area, high pressure keeps us cool and keeps that pattern locked in throughout the day. Highs will only be in the 70s, as periods of rain move through.
Expect these periods of heavy rain to begin Monday morning near and west of the Blue Ridge Parkway. Heavy rain will continue to ride up the Parkway and areas just east of that through the afternoon. Make sure to keep lunch indoors, as flooding may start to occur near creeks and streams.
Depending on how warm we get, we could see a severe storm or two. There’s some rotation in the atmosphere, so the threat for a brief and weak tornado is low but not zero.
Rain may turn a little more scattered at times during the afternoon. Where it does fall, however, it will still be quite heavy.
From Monday morning to Tuesday morning, we expect a widespread 1-3″ of rain for those under the Flood Watch. The exception to that will be parts of the New River Valley and Southside. This amount of rain will cause flooding, especially of creeks, streams and low-lying areas. This may lead to a few road closures and/or basement flooding for those in prone areas.
REST OF THE WEEK
Our front lingers nearby, keeping fog and showers around Tuesday morning. As the front lifts Wednesday, we’ll heat back up with only spotty afternoon storms around. Another front moves in from the west, but it won’t have as much moisture with it. Therefore, we’ll keep it hot and humid with spotty afternoon storms Thursday and Friday.
Once the front passes south and east, temperature come down a touch in time for the Labor Day weekend.
As is usually the case this time of year, the tropics remain very active. There’s no immediate threat, however, to the U.S. just yet. The National Hurricane Center is monitoring four areas of development.
If all four were to get names, they would be Nana, Omar, Paulette and Rene.
We’ll keep you posted on each storm’s progress throughout the next few days.
